Our KW4520G(1)-KW4520LR(1) filter cartridge set includes 2 filters each measuring approximately 4.5” (W) X 20” (L). This dimension is “industry standard” and the “double open end” (DOE) configuration makes it widely compatible with virtually all water filter housing manufacturers that require 4.5” x 20” replacement cartridges.

This cartridge filtration dual replacement set is specifically used for the PWF4520LRDS system which operates in series. First in series is the KW4520G dirt, rust and sediment filter cartridge.The second water filter employs our KW4520LR cartridge. This carbon block water filter can remove chlorine and chemicals for 18,000 gallons with flow rates up to 6 gallons per minute. With the sediment pre-filtration in position the absorptive (chlorine / chemical removal) capabilities of the carbon can be completely exploited without substantial flow rate reduction. Thus the carbon block cartridge will last the estimated 2-4 months without premature failure. Our KW4520LR coconut shell carbon block filter employs Metsorb Lead Removal Media. This media is made in the USA by Graver Technologies and is NSF Certified. The filter cartridge is made in Taiwan. All components and ingredients used to construct the filter cartridges are NSF certified for materials safety.
